Explanation

In AWS CloudFormation, setting the DeletionPolicy attribute to Retain ensures that the resource (in this case, the EC2 instance and its associated data) is not deleted when the stack is deleted. This preserves the instance and its data outside of the stack lifecycle, meeting the requirement to keep everything even if the stack is removed.
